potential low tech hardware
Low tech ≠ efficient
I have an old laptop that is low tech and uses only 15 watts of power. Compared to that my laptop has a general power usage of 35 watts or more on heavy CPU intensive tasks. On face value it seems that the old machine is more power efficient but that is not the case. The amount computing power provided for that 15 watts used is very low and like 15 times lower than the computational grunt provided by the new machine which makes the new machine 5-6 times more efficient.
